Let
L=number of lower tickets sold
U=number of upper tickets sold
then
U=718-L...........(1)
and
9.50L + 8U=6249.50 ..........(2)
Substitute (1) in (2)
9.50L+8(718-L)=6249.50
isolate L and solve
1.5L=6249.50-8*718=505.5
L=505.5/1.5=337
U=718-L=381
Answer:i think is C
Step-by-step explanation:
A=-32 (acceleration is the constant g) integrating with respect to t
v=-32t+vi but initial velocity is equal to zero as it is just "dropped".
h=-32t^2/2+hi, since the initial height is 144 ft
h(t)=-16t^2+144
The object will be at the ground when h(t)=0
-16t^2+144
-16(t^2-9)=0
-16(t+3)(t-3)=0, but since we know t>0
t=3 seconds.
